Mandatory payroll tax begins in 2022 for state long-term care program

A new mandatory state wage tax begins January 2022 to fund the WA Cares Fund, a state long-term care insurance benefit. All employees will pay $0.58 per $100 of earnings through a payroll deduction. King County is required to collect the tax and remit to the Employment Security Department. If you purchase your own long-term care insurance prior to Nov. 1, 2021, you can apply for a permanent exemption to the WA Cares Fund and associated tax. To learn more, go to WA Cares Fund.
